Review Questions

• How does investment impact aggregate demand in an economy?
  • Investment directly influences aggregate demand by adding to the total spending in the economy. When businesses invest in new equipment or infrastructure, they increase their production capacity and create jobs. This not only boosts demand for goods and services but also encourages consumer spending as more people are employed and earning income. Therefore, investment acts as a catalyst for overall economic activity.
• Discuss the relationship between investment and Gross Domestic Product (GDP) within the framework of national income accounting.
  • In national income accounting, investment is one of the key components that contribute to the calculation of Gross Domestic Product (GDP). GDP is computed using the formula: GDP = C + I + G + (X - M), where 'I' represents investment spending. This includes business investments in equipment and structures as well as residential construction. A higher level of investment increases GDP as it reflects greater economic activity and contributes to long-term growth.
• Evaluate the determinants of economic growth with a focus on how investment influences these factors.
  • Economic growth is driven by several determinants, including technological advancements, labor force improvements, and capital accumulation through investment. Investment plays a pivotal role as it enhances the capital stock necessary for production. As businesses invest in new technologies and infrastructure, they boost productivity levels, leading to increased output. Additionally, sustainable levels of investment foster innovation and skill development within the workforce, ultimately creating a virtuous cycle that propels economic growth.
